IMPROVEMENT IN VENTILATING WATER-CLOSET BOWLS.

- Specification forming part of Lctters'Patent No. 138,267, dated April 29, 1873; application filed March 7, 1873.

To all whom it may concern:

Be it known that I, J. VICTOR MATHIVET, of Cleveland, in the county of (Juyahoga and State of Ohio, have invented a new and useful Ventilating Water-Closet Bowl, of which the following is a specification.

This improvement consists in the combination, with a water-closet bowl having a thickened upper edge, in which a groove is formed to receive a strip of suitable packing to form an air-tight joint between the bowl and seat, of an outlet-pipe at the top of the bowl, just under the seat and at the rear side, connecting with a suitable flue or pipe in the wall of the building and leading upward out into the open air, whereby a ventilating draft is created for carrying ofi' the foul air and preventing the stench rrom pervading the room, thus renderable packing to make an air-tight joint between the said bowl and the seat-board which lies over it. 0 is an outlet-pipe, which is to lead to aflue or pipe in or attached to the wall of the room for conducting off the effluvia from the bowl. This will be readily effected by the draft of air caused by said fine, and when the lid of the seat is raised the draft is inward through the seat, so that none of the foul air escapes into the room, but is carried off, thereby forming a perfect ventilator for the water-closet, and thus removing the most objectionable feature in connection with Wetor-closets.

I claim In a water-closet bowl' having a thickened upper edge, the combination of the groove B and packing and the outletpipe (J, for the purposes respectively of forming an air-tight joint between the bowl and seat, and for ventilating the bowl in such manner as to prevent the escape of odors into the apartment, substantially as described.
